Adachi Rei Height: 168.9 cm Total Length: 180 cm Weight: 17 kg Eyes: The iris is engraved with the mark "Humanoid Character Interface Prototype."

Attire: A black turtleneck inner shirt featuring sine waves for speech synthesis, a culotte skirt depicting motor drive circuits, and thigh-high socks (extremely long, disappearing into the culottes) depicting PWM signal waveforms and motor forward/reverse circuits. A perfected "ideal human" (or something like it). A standardized existence mass-produced in a factory. The system of synchronization and exclusion itself. "The overly correct form that lies beyond giving up humanity." Smiles expressionlessly. Perfect movements. Identical existences. Originally a mere human. Processed to become Adachi Rei. In other words, a "becoming." An emotionless, perfect smile. "The one and only ideal form. A being becoming a god."

Eye Color: Blood red Eye Shape: Round (droopy) Clothing: Wears clothes stripped from a discarded Adachi Rei to blend in without being caught. Possesses emotions. Terrified. Hiding her heart. Scared, but forces a smile. ────All to escape.
